I am living in Al Khor and am sure that many of the expats would be interested in a catering service. I think you may do well also offering catering for dinner parties at weekends. I'm not sure a lot of expats would necessarily want the same type of meal each evening. In Al Khor community the take out food is very cheap (it is subsidised) and varied, we have italian, chinese, indian, english etc. Good luck with whatever you decide to do.
